Abstract
In this paper I show how to calculate the effect of a nearby Pearl vortex or antivortex upon the critical current Ic(B) when a perpendicular magnetic induction B is applied to a planar Josephson junction in a long, thin, superconducting strip of width W much less than the Pearl length Λ=2λ2/d, where λ is the London penetration depth and d is the thickness (d<λ). The theoretical results provide a qualitative explanation of unusual features recently observed experimentally by Golod et al. [Phys. Rev. Lett. 104, 227003 (2010)] in a device with a similar geometry.
